Application filed August 19,1905. Serial No. 274,881.

nois, have invented a certain new and usefulImprovement@Printing-Machines, of which the following is a specmcation.

The olnect of the present invention is to provide a simple yet effectivemechanismfor printing from a form of type, such type being either of thecharacter commonly employed in printing-presses or, if desired, of thecharacter better adapted for setting np by nnskilled hands and having aprinting-face at one end and a display-face at the other. 1n carryingout the invention to this end I employ a suitable frame having avertically-ad-4 justablepressure-roller and means for throwing the sameto operative and inoperative positions. Coacting with such frame is acarriage adapted to receive the chase in which the form of type has beenset up, and inter# mediate of such form and the vertically-adinstablepressure-roller I employ an ink-ribbon carried, preferably, by a rollateach end of the carriage, suitable mechanism being combined therewithfor moving .said ribbon step by step at predetermined s eed, so as topresent a fresh surface thereof or successive rinting movements of thecarriage and the orm of type supported therein.

The invention is illustrated in the accompanying drawings, in which-Figure 1 is a side elevation vof a printingmachine employing myinvention. Fig. .2 is a central longitudinal section thereof.- Fig. 3`isa plan view, certain portions being shown in section. Fig. 4 is a detailvertical section on the line 4 4, Fig. 3; and Figs. 5 and 6 are detailviews illustrating portions of the ribbon supporting and operatingmechanism.

Referring to the drawings, in which similar letters of reference denotecorresponding parts, the frame of the machine comprises, generallyspeaking, two side plates A A', which may be provided with cross bars orbraces c a. Said plates are provided with vertical slots a2, throughwhich extend the ends of the shaft b of the pressure-roller B. The endsof said shaft arejonrnaled in arms C C', each of which is pivoted at cto the outer face of one of the side plates of the frame, the distantend of each arm being downturncd, asshown at c', and provided with thetoe c2.

frame.

D designates a shaft ionrnuled in the side plates A A and projectingrtherethrough, the ends of' said shaft being provided with cams d, saidshaft and eums being operated, by means of a suitable finger-piece tobring the cams d into eoaetion with the toes ci of the hinged arms tothereby elevateI and depress the pressl'lre-roller B, throwing the sameto operative. or inoperative positions, as

desired. Pivotally mounted lat. c upon the outer face of each of thehinged roller-carrying arms is a loelt E, the lower end whereof isprovided with a linger 1', adapted when said lock E is rocked upon itspivotal point (the pressure-roller B being depressed) to eoact withtheshaft l). Each of said locks E.

includes an upward extension f2, projtw-ting into the path of a sto iformed upon the carri age, as presently exi'ilained. The lower arm e ofeach of said locks coacts with a guide- Stop e, limiting the movement ofsaidlower arm e3.4 Coil-springs F l", the lower ends whereof areconnected with the hinged rollervcarrying arms (l C and the upper endswith adjusting-nntsf, serve to exert upward tensionupon said arms and tomovel the pres sure-roller B to operative iosition.

The carriage overlying the mechanism just described includes the sidemembers G G and the end members g g. Adjacent to their lower edges theside members G G are provided with guide-ribs g2, coacting with rabbetsor grooves g:i in the plates A A of the Each of said side membersG G isalso provided with a rack g4, -which coacts with a pinion g5, carried bythe shaft b of the pressure-roller B, so that as the carriage is movedforward, the racks' g4 and pinions g5 being in engagement, thepressure-roller will be driven. This, however, does not apply to therearward movement of said carriage, since the pinions g5 will be thrownout of engagement with said racks, ashereinafter explained.

Supported by the carriage in any suitable manner is the chase in whichthe type are sot up. This may be of any desired construction, and I havehere shown, merely for the .purpose of disclosure, a rectangular chasenot illustrated in the drawings.

same have been set up from being pushed up-A wardly during the printingoperation.

I here remark that it is obvious that, if desired, the interior of thechase described may be removable,so that a 'chase either of theconstruction alluded to or of another and different construction maybeset within the same and securely fastened in such position. These andother details in connection with the form of the type-supportingmechanism may be varied at will without departing from the spirit of theinvention. The chase may be secured to the carriage in any suitablemanner-as, for instance, by the latches h4.

At either end the carriage is provided with brackets (preferablyadjustable) carrying rolls or spools on which the ribbon I may be wound.The brackets L L at the rearward end of the carriage are provided eachwith the upwardly-extending portion Z and the angular downturned portionZ, the forward end of the latter having the beveled portion Z2, itsouter face carrying the lock-operating boss Z3, coacting with the upperend c2 of the lock E. The beveled portion Z2 of each bracket L coactswith a sheave Z5, carried by an ear Z6 on one of the hingedroller-carrying arms C C', so as to depress said roller in advance ofthe coaction of the boss Z3 and the arm e2, such coaction resulting inmoving the locks E on their pivotal points e and throwin the fingers einto engagement with the sha t I), thereby locking said pressure-rollerin inoperative position at the conclusion of the forward (printing)movement of the type-carriage. Each of the brackets Lis providedv withthe set-screw Z4, engaging with one or another of a series of threadedorifices Z7 in the side men'ibersG G of the carriage.

Mounted upon the upwardly-extending portion Z of one of the brackets Lis a sleeve m, through which extends a stub-shaft m', to the outer e-.idwhereof is keyed or otherwise secured a knurled nut m2. Keyed orotherwise securedto said sleeve m is a ratchetwheel m3, with whichcoacts the upper end of a lever m, pivoted upon said stub-shaft m, vitslower end projecting downwardly and adapted to coact with a stop-pin m5,carried on the outer face of the frame-plate A. Inside the bracket L thesleeve mis provided with a clutch member m", inwardly pressed by meansof coil-spring m7, said clutch member being provided with a pin1n8,coacting with a slot m9 in said sleeve, and the inner face of saidmember being serrated in usual manner to coact with the clutch memberm1", keyed i with an oriice in the head ny ol' the ribbonspool N. Aswill be seen, the forward movement of the carriage brings thc lever 1n*and pin mi into coawtion, therebyr through thc ratchet m turning thesleeve m, and' thereby the clutch member ml" andthe ribbon-spool N,carried by said clutch member. If desired, I may employ a pawl m,coacting with the ratchet m3, to preclude accidental (independent)movement of said ratchet. ()n the other side the upwardly-extendingportion Z of the bracket L is provided with a bearing 0, through whichextends a stub-shaft o, having the collar o adjacent to one end and theknurled operating-nut o2 at thev other. `Between the collar o vand thebearing O the stub-shaft is provided with a coil-spring 0'". Saidstub-shaft o cacts with the other end n of the ribbon-spool N.

The brackets P P at the forward end 4of the carriage may be similar inconstruction to the brackets L, save that no provision need be herelocated for driving the ribbon-spool. To this end one of the stub-shaftsp may be provided with a col/lar similar to the collar o andacoil-spring similar to the coil-spring o3, permitting the ribbon-spoolN to be readily placed in position on the inward ends of saidstub-shafts, the ribbon being fed from this spool to the spool N in themanner above described.

R designates a roll the ends whereof are journaled inthe brackets P P atthe for .vard end of the carriage. 1' designates a similar roll, whichmay be convenientlygjournaled in a recess formed in the end member h ofthe chase or type-supporting frame. The rolls lr and r2 at the forwardend of the carriage are similarly arranged, and all these rolls will beof a length somewhat greater than the width of the ink-ribbon I.Initially the ribbon is wound upon the spool N. It is then passed overthe roll R, under the roll r, underthe roll r2, over the roll 1", andthen made fast to the spool N. This brings it 'directly under the facesof the type set up in the chase or type-frame above described. At itsrearward end the carriage may be provided with the operating-handle N2.

S designates a feed-board, here shown as provided 'with adjustable sideand end guides S S2 S3. If desired, the forward end -of said feed-boardvmay be provided with a hood s to protect the upper surface. of the sheetpile laid on said board from the inkribbon I.

The drawings illustrate the position of the several parts midway of theprinting operation.l Starting at the beginning this operation is asfollows: The carriage is rstpressed forward, whereupon the beveledsurfaces Z2 are brought into Contact with the sheaves Z5,

los

or otherwise secured on the stub-shaft m. depressing the pressure-rollerB. Next the f The inner face ofthe clutch member m1 is provided with apin m, adapted to coact bosses Z3 are brought into contact with theupper arms e2 of thev locks E, tl1ereby throw- ISO ing said locks toengaging position and se the pile laid upon thev feedoard S may thenV bepressed forward, so that its forward end shall overlie the saidpressure-roller. If now the carriage be moved rearward, the beveledsurfaces p of the brackets at the forward end of the carriage will rideover the sheaves l5, and a momentlater the bosses p2, making contactwith the upwardly-extending arms e'z of the lock E,vwill throw said lockto inoperative position, thereby leaving the pressure-roller free tosise after said beveled surfaces p have been moved out of contact withthe sheaves Z5. If now the carriage be again moved rearwardly, themoment the beveled surfaces p and the iieaves Z5 are thrown out ofcoaction the pressure-roller will rise, thereby moving the sheet upwardand into contact with the characters on the printingvsurfaces ofthe typeheld in the chase supported by the carriage and said chase, said sheet,and said pressure-roller moved forward in unison, the impression beingprinted upon said sheet meanwhile. At the conclusion of the printingoperation the sheet is passed forward by the pressure-roller and may bereceived ina suitabletray, (not shown,) if desired. This forward(printing) movement of the carriagev also causes, through the coactionof the lever m4 and pin m5, the feeding of the ribbon from the spool Nto the spool N so that for each printing movement of the carriage afresh surface of the ink-ribbon I will be interposed between thetype-faces and the impression-sheet.
